[X4U] Roaming wireless options

[Jim Soriano]

On my 1.2Ghz iBook 14" I use a D-Link DBT-120 USB Bluetooth adapter  
to connect to my Sony Ericsson T610, then use GPRS to connect to the  
internet via T-Mobile here in California.  Coverage and network  
availability seems to be about 85% of their voice footprint; i.e.  
there are occasional locations where I've tried to use it and didn't  
successfully get a GPRS data connection.

Connection speed is rather slow, about 56Kbps to maybe 90Kbps real  
throughput.  It is adequate for most of my email needs when I'm not  
near a Wi-Fi hotspot.  (Wi-Fi over public hotspots, pay or free,  
provides MUCH better performance.)

There are several Apple Knowledge Base articles that provide more  
insight.  The main one is here:

Follow the links in the article for more details.

T-Mobile's GPRS data network in the US is far from being leading  
edge.  Cingular has probably the best performance with their GPRS/ 
EDGE implementation.
